Description
Die Erfindung betrifft eine Verbindungsanordnung für Fluidleitungen mit einer weiteren fluidfördernden Komponente, bei der die Fluidleitung mindestens einen radial nach außen weisenden Bund aufweist, der mittels einer Halterung axial gegen die weiteren fluidfördernde Komponente verspannbar ist.The invention relates to a connection arrangement for fluid lines with a further fluid-conveying component, wherein the fluid line has at least one radially outwardly facing collar which is clamped by means of a holder axially against the further fluid-conveying component.
Derartige Verbindungsanordnungen sind seit längerem in vielfältigen Ausführungsformen im Einsatz.Such connection arrangements have long been in various embodiments in use.
Die
Eine derartige Halteplatte ist jedoch nur bei Rohrleitungen einsetzbar, die entweder nur an einem Ende einen Bund aufweisen oder ein zweiter Bund erst nach Aufstecken der Halteplatte auf die Fluidleitung an der Fluidleitung erzeugt wird.However, such a holding plate can only be used in pipelines which either have a collar at one end or a second collar is produced only after attaching the holding plate on the fluid line to the fluid line.
Die
Die
Bei allen diesen Anordnungen muss jedoch die Fluidleitung so lange separat in ihrer Position gehalten werden, bis der Haltehebel bzw. die Flanschen in Position liegen. Anderenfalls würde die Fluidleitung aus ihrer Position herausfallen. Bei der Montage sind also mehrere separate Teile zu handhaben.In all of these arrangements, however, the fluid conduit must be kept in position separately until the retention lever or flanges are in position. Otherwise, the fluid line would fall out of position. During assembly, therefore, several separate parts to handle.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbindungsanordnung der eingangs geschilderten Art zu schaffen, die eine sichere, druckdichte Verbindung der Fluidleitung mit der weiteren fluidführenden Komponente bei einfacher Montage auch an Fluidleitungen mit zwei Bunden ermöglicht.The invention has for its object to provide a connection assembly of the type described above, which allows a secure, pressure-tight connection of the fluid line with the other fluid-carrying component with a simple installation on fluid lines with two coils.
Diese Aufgabe wird dadurch gelöst, dass die Halterung der Verbindungsanordnung mindestens eine U-förmige seitliche Aufnahme und mindestens eine seitlich zu der Aufnahme versetzte Verschraubungsbohrung aufweist, wobei die mindestens eine U-förmige Aufnahme durch zwei Schenkel gebildet ist, die seitlich von der Verschraubungsbohrung sich in einer vorbestimmten Länge von der Halterung weg erstrecken, wobei die vorbestimmte Länge der Schenkel so bemessen ist, dass sie bei plastischer Verformung die Fluidleitung mindestens mehr als zur Hälfte umschließen.This object is achieved in that the holder of the connection assembly has at least one U-shaped lateral receptacle and at least one laterally offset to the receptacle Verschraubungsbohrung, wherein the at least one U-shaped receptacle is formed by two legs which laterally from the screw hole in a predetermined length extend away from the holder, wherein the predetermined length of the legs is dimensioned so that they enclose the plastic line at least more than half of the fluid line.
Diese Anordnung hat den Vorteil, dass die Halterung seitlich auf die Fluidleitung aufsteckbar ist und durch die plastische Verformung der Schenkel der U-förmigen Aufnahme um die Fluidleitung herum unverlierbar an der Fluidleitung befestigbar ist.This arrangement has the advantage that the holder is laterally attachable to the fluid line and by the plastic deformation of the legs of the U-shaped receptacle around the fluid line around captive on the fluid line can be fastened.
In einer Weiterbildung der Erfindung weisen die U-förmigen Aufnahme mindestens einen Entlastungsbereich auf, in dem Lücken, Nuten, Hohlräume oder andere Materialreduktionen angeordnet sind.In a development of the invention, the U-shaped receptacle has at least one relief region, in which gaps, grooves, cavities or other material reductions are arranged.
Es hat sich herausgestellt, dass bei der plastischen Verformung der meist einen rechteckigen oder quadratischen Querschnitt aufweisenden Schenkel im ins Innere der U-Form weisenden Teilbereich der Schenkel durch die in diesem Bereich bei der Umformung auftretenden tangentialen Materialstauchungen eine axiale Verdickung des Querschnitts auftritt. Die axiale Auflagefläche der Halterung, die bei Verspannung gegen den Bund der Rohrleitung drücken soll, ist damit nicht mehr eben. Damit ist in besonderen Fällen, beispielsweise schwingender Belastung der Verbindung eine dauerhaft druckdichte Verbindung der Klimaleitung mit der weiteren fluidführenden Komponente nicht mehr sichergestellt.It has been found that in the plastic deformation of the legs, which generally have a rectangular or square cross-section, in the sub-region of the limbs pointing in the interior of the U-shape an axial thickening of the cross-section occurs due to the tangential material compressions occurring in this region during the deformation. The axial bearing surface of the bracket, which should press against the federal government of the pipeline in tension, is thus no longer flat. This is no longer ensured in special cases, such as vibratory loading of the compound a permanently pressure-tight connection of the air conditioning line with the other fluid-carrying component.
In den erfindungsgemäßen Entlastungsbereichen kann bei der Stauchung der der Fluidleitung zugeordneten Bereiche das Material in den Lücken, Nuten, Hohlräumen oder anderen Materialreduktionen zusammenfließen. Dadurch wird im Wesentlichen verhindert, dass eine Verdickung des Querschnittes an den Schenkeln auftritt. Die zwischen den Entlastungsbereichen noch auftretenden örtlichen Verdickungen sind meist derart gering ausgeprägt, dass die dauerhaft sichere Funktion der Verbindung nicht gefährdet ist.In the relief regions according to the invention, the material in the gaps, grooves, cavities or other material reductions may flow together during the compression of the areas assigned to the fluid line. This substantially prevents thickening of the cross-section on the legs from occurring. The local thickening still occurring between the discharge areas are usually so small that the permanently reliable function of the connection is not endangered.
Anhand der Zeichnung wird nachstehend ein Beispiel der Erfindung näher erläutert.With reference to the drawing, an example of the invention will be explained in more detail below.
